Remote access minikube cluster远程访问minikube k8s集群

minikube是启动一个虚拟机来模拟单节点环境，容器运行在单独的网络环境

可以看到192.168.49.2:8443是api server地址，是虚拟的ip

(base) [root@localhost access]# kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority: /root/.minikube/ca.crt
    extensions:
    - extension:
        last-update: Fri, 19 Apr 2024 14:52:06 CST
        provider: minikube.sigs.k8s.io
        version: v1.32.0
      name: cluster_info
    server: https://192.168.49.2:8443
  name: minikube
contexts:
- context:
    cluster: minikube
    extensions:
    - extension:
        last-update: Fri, 19 Apr 2024 14:52:06 CST
        provider: minikube.sigs.k8s.io
        version: v1.32.0
      name: context_info
    namespace: default
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    client-certificate: /root/.minikube/profiles/minikube/client.crt
    client-key: /root/.minikube/profiles/minikube/client.key

只能在本机访问，所以无法远程访问

(base) [root@localhost ~]#  docker port minikube
22/tcp -> 127.0.0.1:32792
2376/tcp -> 127.0.0.1:32791
5000/tcp -> 127.0.0.1:32790
8443/tcp -> 127.0.0.1:32789
32443/tcp -> 127.0.0.1:32788

需要通过参数--listen-address=0.0.0.0  --apiserver-ips=主机ip地址参数来重启minikube才能远程访问：

1、如果已经创建了minikube，需要先minikube delete删除

2、重新启动minikube start  --listen-address=0.0.0.0  --apiserver-ips=本机ip地址

3、启动成功后，检查监听网络。看到8443/tcp -> 0.0.0.0:32769对应的本机的端口是32769，那么远程通过本机ip地址:32769来访问api server

(base) [root@localhost access]#  docker port minikube
22/tcp -> 0.0.0.0:32772
2376/tcp -> 0.0.0.0:32771
5000/tcp -> 0.0.0.0:32770
8443/tcp -> 0.0.0.0:32769
32443/tcp -> 0.0.0.0:32768

4、配置远程访问的kubectl参数，需要config（就是kubectl config view命令的输出），修改config中的server地址为第3步的ip端口；config文件中指定的ca.crt、client.crt和client.key三个文件，就可以在远程访问minikube的k8s了。

E:\k8s>kubectl.exe --kubeconfig C:\Users\Administrator\.kube\config get nodes
NAME       STATUS   ROLES           AGE   VERSION
minikube   Ready    control-plane   24m   v1.28.3
